Little Jetfighter of the Sea
Little Jetfighter of the Sea - Belemnite
Belemnites are an extinct group of cephalopod (squid -like creatures) that were around for millions of years.
They were built for speed, like a squid tucked into the end of a jet fighter body.
Possibly they used their speed and manoeuvrability to collide with and stun their prey.
